The boom support clamp has a clever feature whereby a set screw can be inserted into the upper hole (arrowed) which splays the clamp apart allowing it to be slid down the boom without damaging the surface finish

I really like the idea of this, saves wedging the usual screwdriver in between the boom clamps.

Little things like this, and the attention to detail that Kasama incorparates is what makes these machines such a pleasure to build and work on.

With the tail rotor being matched and checked, does it still need to be pulled apart, checked and reassembled with loctite, or is it pre assembled ready to go?

No I'd leave it assembled - it shouldn't need Loctite anyway because of the Nyloc nuts - Kasama started putting Loctite on after years of production of the tail after a couple of reports of grips coming off - this was probably due to uneven bases of the M3 locknuts acting as an impact driver. The nuts now are all machined flat and matched to the rotor hub.

On mine i will use Castle ice2 120A and Scorpion 4035-530.
I tried to set up my ESC in the castle link program (governor) giving main gear 104 and pinion 11 teeth and i saw that on 94.3% or ESC power i get 2200 RPM.
How you can get that 2400 RPM? Unless you will run it without governor. Is that right?

Only way is to use a different ESC - you are stuck with the 9.45:1 ratio - a Jive will give these figures!

I'd certainly try out your CC and see if you like it - the Dune, like all other Kasama helis, is very effiicient and doesn't need blindingly high HS. I don't understand why the different ESC give such different results

I saw the Kasama Dune flying today at our local club,thanks John.My non technical comments are,It looks great in the air,that canopy is growing on me.Its so damn quiet,Its the quietest 600 size heli Ive heard.It also had some legs when needed and that was at a fairly low HS.

At last i bought Kontronik and i have to ask for throttle set up on my DX8 with my 530KV motor. Is that figures you gave me? Can you help me on that?
